Penske Racing says in a Monday statement it is evaluating its options for the No. 22 Dodge.

The split comes after six bumpy years for Busch and Penske. Although Busch won 10 races since joining the organization in 2006, his meltdowns on his team radio were notorious and two crew chiefs have left the team in the last three years.

Busch also sparred this season with the media more than usual, and was fined $50,000 last month by NASCAR after he was caught on video by a fan being verbally abusive to an ESPN reporter.
